Atlas Pro Step On Snowboard Bindings - Stone 2027 FAQ
What makes Atlas Pro Step On different from regular Atlas Step On?
Atlas Pro Step On features a Forged Carbon spine in the highback (S1 Step On Pro Forged Hybrid) and an all-new Drive Frame Hi-Flex EVA bushing. 8/10 flex, 10/10 all-mountain score, and 9/10 performance for ultimate all-mountain power with Step On convenience.
Is Forged Carbon worth the premium over nylon?
Yes. Forged Carbon is four times stronger than nylon at half the weight, enabling ultra-lightweight, hyper-responsive components. The carbon spine in the highback transmits your movements directly to the board for instant edge response.
What's the Drive Frame bushing and how is it different?
Drive Frame is an exclusive new design delivering increased response. Combined with Hi-Flex EVA, it provides cushioning and damping while maintaining a precise, reactive feel. Purpose-built for the Atlas Pro Step On.
Is the weight still reasonable at 1.80 kg?
Yes. At 1.80 kg (pair), it's competitive with top performance bindings. The Forged Carbon highback and Drive Frame bushing are lightweight engineering, not weight penalties.
